mysqld.service: control process exited, code=exited status=1

[root@pc4 mysql]# systemctl status mysqld

看了MySQL的错误日志，发现：

2023-01-22T14:11:12.679082Z 0 [ERROR] [MY-000067] [Server] unknown variable 'default-file=/etc/my.cnf'.

原来是“default-file=/etc/my.cnf”少了一个“s”，应为“defaults-file=/etc/my.cnf”。

修改文件，重新加载

systemctl daemon-reload

启动，成功了

[root@pc4 mysql]# systemctl status mysqld
